RELATED APPLICATIONS

This application claims priority under 35 U.S.C. Section 119(e) to U.S. Provisional Patent Applications Nos. 61/107,945, 61/107,935, and 61/107,921, each of which was filed on Oct. 23, 2008, the entire disclosures of which are hereby incorporated by reference in their entirety.

BACKGROUND

Mobile communication devices (e.g., wireless phones) have become an integral part of everyday life. However, the form factor employed by conventional mobile communications devices is typically limited to promote mobility of the device.

For example, the mobile communications device may have a relatively limited amount of display area when compared to a conventional desktop computer, e.g., a PC. Therefore, conventional techniques used to interact with a desktop computer may be inefficient when employed by a mobile communications device. For example, traditional menus may consume a significant amount of display area of the display device thereby limiting the amount of display area that is available for content.

SUMMARY

A mobile communications device user interface is described. In an implementation, a method is implemented by a computing device that includes displaying content in conjunction with a first level of a hierarchical menu in a user interface on a display device of the computing device. Responsive to receipt of an input to navigate to a second level of the hierarchical menu that is a sublevel of the first level, the second level in displayed conjunction with the content on the display device, the content having a reduced display richness when displayed in conjunction with the second level than when displayed in conjunction with the first level.

In an implementation, one or more computer-readable storage media include instructions that are executable by a mobile communications device to cause output of a user interface on a touchscreen of the mobile communications device. The user interface has a hierarchical structure in which a root level of the hierarchical structure includes a first menu item that is selectable via the touchscreen to initiate a primary action and a second menu item that is selectable to cause display of a sublevel of the hierarchical structure that includes a plurality of menu items. One or more of the plurality of menu items are selectable to initiate a respective action and at least one of the plurality of menu items is selectable to cause display of another sublevel of the hierarchical structure.

In an implementation, a mobile communications device includes a touchscreen, a processor, and memory configured to maintain an operating system. The operating system is executable on the processor to display a user interface on the touchscreen that is scrollable via a gesture received via the touchscreen. The user interface is configured for display on the touchscreen to include one or more menu items when the user interface is not scrolled and configured to not display at least a portion of the one or more menu items when the user interface is scrolled.

DETAILED DESCRIPTION

Overview

Mobile communications devices typically have a small form factor to aide mobility of the mobile communications device. For example, the mobile communications device (e.g., a mobile phone) may be configured with a relatively minimal amount of display area and limited input devices (e.g., a keypad) so that the device may be easily transported. Consequently, traditional techniques used to interact with a conventional computer (e.g., a desktop PC) may be frustrating when used in conjunction with a mobile communications device.

For instance, use of a conventional menu and tool bar may consume a significant amount of display area of a display device, even when not being used. Consequently, conventional menus may limit the amount of display area that is available to display content, such as images, contact information, documents, and so on.

In an implementation, a user interface is described that limits the amount of “chrome” this is displayed when the menu is not in use. For example, the menu may be configured to include a root level having a menu item that is selectable to initiate a primary action and another menu item that is selectable to navigate “down” through the hierarchy to additional actions. In this way, the user interface may include a menu that includes a primary action that is likely to be initiated by a user (e.g., output based on the type of content that is displayed in conjunction with the menu) without forcing the user to navigate to a submenu yet still provide the user with an option to navigate through the hierarchy to access additional actions. Further discussion of hierarchical navigation may be found in relation to FIGS. 2 and 3.

In another implementation, a user interface is described that configures underlying content to provide an indication of a level at which a user has currently navigated in a hierarchical structure. Continuing with the previous example, the user may navigate through successive levels of the hierarchy to locate a desired action. During this navigation, the content that is displayed in conjunction with the menu may be displayed in succession as having a decreased display richness, e.g., darker, less color, less contrast, and so on. Thus, the content may be used to reflect a relative level of the hierarchy and thus limit the amount of chrome that was traditionally utilized to indicate a current location within the hierarchy. Further discussion of display richness and hierarchical levels may be found in relation to FIGS. 4 and 6.

In a further implementation, a user interface is described that is configured to temporarily hide at least a portion of a user interface when scrolling. For example, the user interface may be configured to display a menu as an overlay over a display of content. When the content is scrolled, the menu may be output as part of an animation to make it appear that the menu follows inertia of the scrolling content, e.g., direction and speed, to hide at least a portion of the menu. When the scrolling stops, the animation may cause the menu to reappear, e.g., as the scrolling is slowed. Further discussion of scrolling may be found in relation to FIG. 5.

In the following discussion, a variety of example implementations of a mobile communications device (e.g., a wireless phone) are described. Additionally, a variety of different functionality that may be employed by the mobile communications device is described for each example, which may be implemented in that example as well as in other described examples. Accordingly, example implementations are illustrated of a few of a variety of contemplated implementations. Further, although a mobile communications device having one or more modules that are configured to provide telephonic functionality are described, a variety of other mobile devices are also contemplated, such as personal digital assistants, mobile music players, dedicated messaging devices, portable game devices, netbooks, and so on.

Example Implementations

FIG. 1 is an illustration of an example implementation 100 of a mobile communications device 102 in accordance with one or more embodiments of devices, features, and systems for mobile communications. The mobile communications device 102 is operable to assume a plurality of configurations, examples of which include a configuration as illustrated in FIG. 1 in which the mobile communications device 102 is “open” and a configuration in which the mobile communications device 102 is “closed” as illustrated in FIGS. 2-5.

The mobile communications device 102 is further illustrated as including a first housing 104 and a second housing 106 that are connected via a slide 108 such that the first and second housings 104, 106 may move (e.g., slide) in relation to one another. Although sliding is described, it should be readily apparent that a variety of other movement techniques are also contemplated, e.g., a pivot, a hinge and so on.

The first housing 104 includes a display device 110 that may be used to output a variety of content, such as a caller identification (ID), contacts, images (e.g., photos) as illustrated, email, multimedia messages, Internet browsing, game play, music, video, and so on. In an implementation, the display device 110 is configured to function as an input device by incorporating touchscreen functionality, e.g., through capacitive, surface acoustic wave, resistive, optical, strain gauge, dispersive signals, acoustic pulse, and other touchscreen functionality. The touchscreen functionality (as well as other functionality such as track pads) may be used to detect gestures, further discussion of which may be found in relation to FIG. 5.

The second housing 106 is illustrated as including a keyboard 112 that may also be used to provide inputs to the mobile communications device 102. Although the keyboard 112 is illustrated as a QWERTY keyboard, a variety of other examples are also contemplated, such as a keyboard that follows a traditional telephone keypad layout (e.g., a twelve key numeric pad found on basic telephones), keyboards configured for other languages (e.g., Cyrillic), and so on.

In the “open” configuration as illustrated in the example implementation 100 of FIG. 1, the first housing 104 is moved (e.g., slid) “away” from the second housing 106 using the slide 108. Other implementations are also contemplated, such as a “clamshell” configuration, “brick” configuration, and so on.

The form factor employed by the mobile communications device 102 may be suitable to support a wide variety of features. For example, the keyboard 112 is illustrated as supporting a QWERTY configuration. This form factor may be convenient to a user to utilize the previously described functionality of the mobile communications device 102, such as to compose texts, play games, check email, “surf” the Internet, provide status messages for a social network, and so on.

The mobile communications device 102 is also illustrated as including a communication module 114. The communication module 114 is representative of functionality of the mobile communications device 102 to communicate via a network 116. For example, the communication module 114 may include telephone functionality to make and receive telephone calls. The communication module 114 may also include a variety of other functionality, such as to capture content, form short message service (SMS) text messages, multimedia messaging service (MMS) messages, emails, status updates to be communicated to a social network service, and so on. A user, for instance, may input a status update for communication via the network 116 to the social network service. The social network service may then publish the status update to “friends” of the user, e.g., for receipt by the friends via a computer, respective mobile communications devices, and so on. A variety of other examples are also contemplated, such as blogging, instant messaging, and so on.

The mobile communications device 102 is also illustrated as including a user interface module 118. The user interface module 118 is representative of functionality of the mobile communications device 102 to generate, manage, and/or output a user interface 120 for display on the display device 110. A variety of different techniques may be employed to generate the user interface.

For example, the user interface module 118 may configure the user interface 120 to output a root level of a hierarchical menu. In the illustrated example, output of the root level includes a first menu item 122 that is selectable to initiate a primary action “send.” A second menu item 124 is also included that is selectable to navigate to a submenu of the hierarchy, which is illustrated as “more” in the figure. In this way, the output of the root level has limited intrusion on an amount of display area of the display device 110 that is available to output underlying content 126 yet still provides at least a single action that is selectable without navigating through the hierarchy. Additional menu items may then be displayed by navigating through the hierarchy, further discussion of which may be found in relation to the following figure.

FIG. 2 is an illustration of a system 200 showing the mobile communications device 102 of FIG. 1 in an example implementation that shows an animation that is output in response to navigation to a submenu. Three different stages of the mobile communications device 102 are illustrated in FIG. 1 as a first stage 202, a second stage 204, and a third stage 206.

In the first stage 202, the display device 110 is illustrated as displaying the user interface 120 to include a root level of a hierarchical menu having the first and second menu items 122, 1224 as previously described. In this example, the menu is displayed as an overlay “over” the content 126, which is an image as previously described. For example, the image may be captured using an image capture device of the mobile communications device 102, an image obtained via the network 116, and so on.

As previously described, the first menu item 122 of the root level of the hierarchical menu is selectable to initiate an action. This action may be selected by the user interface module 118 from a variety of different actions, such as based on the underlying content 126 that is currently being displayed in the user interface 120, applications that are currently “running” on the mobile communications device 102, and so on. Thus, the user interface 120 may be configured to enable selection of an action that is likely to be of interest to a user without forcing the user to first navigate “through” a hierarchy. Less likely actions may then be positioned accordingly at successive levels of the hierarchical menu.

In the first stage, a user's finger 208 is illustrated as selecting the second menu item 124 “more.” This selection is received using touchscreen functionality of the display device 110. In this example, selection of the menu item 124 initiates output of an animation as further illustrated in the second stage 204 of the mobile communications device 102.

In the second stage 204, menu items that are included in a submenu of the hierarchy are animated to expand outwards in a radial manner from the point of selection on the display device, e.g., the menu item 124 “more” of the first stage 202. In the illustrated example, text is not included on the menu items in the sublevel during the expansion, although it should be readily apparent that in alternate embodiments text may be included on the menu items.

Additionally, the menu items themselves may also be animated to expand in size from the initiating menu item. For example, the menu items may expand outwards from the initiating menu item (e.g., the second menu item 124) and expand in size until reaching a final placement and size as shown in the third stage 206. Text in the menu items may also expand with the menu items in an embodiment.

The menu items in the third stage 206 correspond to a sublevel of the hierarchical structure of the root level shown in the first stage 202. In an implementation, the menu items that are selectable to initiate an action involving the content 126 that are included in the sublevel are less likely to be of interest to a user that a primary action that corresponds to the first menu item 122 in the root level. Further, the second menu item 124 “more” has been changed to a sublevel menu item 210 “back” to cause navigate back “up” through the hierarchy to the root level. In this way, a user may use a single portion of the user interface 120 to navigate back and forth between levels of the hierarchy. One or more menu items in the sublevel are also selectable to cause output of an additional level in the hierarchy and thus the hierarchy may mimic a tree structure having a variety of different branches and levels, further discussion of which may be found in relation to the following figure.

FIG. 3 is an illustration of the mobile communications device of FIG. 1 in an example implementation of a system 300 that shows animation and navigation to an additional submenu of the hierarchical menu shown in FIG. 2. Like FIG. 2, the current figure includes first, second, and third stages 302, 304, 306 of an animation that is output in response to navigation through a hierarchical menu.

In the first stage 302, the user's finger 208 is illustrated as selecting a menu item 308 “edit” that is to be applied to the underlying content 126. In response, menu items to be included in another submenu are animated as expanding outwardly and growing in size as illustrated in the second stage 304. Completion of the animation is illustrated in the third stage 306 in which the other sublevel (i.e., the third level of the hierarchical menu) is displayed as having menu items “crop,” “tag,” and “make profile.” As before, the menu item 308 has changed to a “back” menu item 310 to permit navigation back through the hierarchy.

Thus, as shown in FIGS. 2 and 3, a menu technique is described that may be utilized by a touchscreen user interface. At the root level 202, this technique reduces available actions in a specific context to only two menu options: a primary and a secondary option. The primary action is the most prominent menu item (e.g., the first menu item 122) and may be selected to be the “most important” action in any given context, e.g., most likely to be used.

When selected, the second menu item 124 causes a cascade of the next level of actions to expand outwards radially from the touch point. This helps to make the sub-menu actions visible even while the user's finger 208 occludes the display device 110, which is an ergonomic consideration for touch interfaces. Additionally, the placement and specific design of the menu techniques does not involve permanent menu bars on the screen, again leaving more room for display of content 126 on the display device 110. Thus, as described in this example a user may navigate through various levels of a hierarchy to locate and utilize desired actions. A variety of different techniques may be employed to describe “where” in the hierarchy the user is currently located, i.e., what level and/or branch is currently being displayed, an example of which may be found in relation to the following figure.

FIG. 4 is an illustration of the mobile communications device 102 of FIG. 1 in an example implementation 400 that shows content having reduced display richness when displayed in conjunction with successively lower levels of a hierarchical menu. In this example, first, second, and third stages 402, 404, 406 are illustrated that correspond to successive levels of a hierarchy. The first stage 402 corresponds to the root level as previously described in relation to the first stage 202 of FIG. 2 and the second stage 404 corresponds to the sublevel as previously described in relation to the third stage 206 of FIG. 2. The third stage 406 corresponds to the third stage 306 of FIG. 3.

In each of the successive stages, display of the underlying content 126 is changed to indicate a respective level in the hierarchy that is currently being displayed. For example, the display richness of the underlying content may be reduced as a user navigates “down” through the hierarchical levels. The display richness may be altered in a variety of ways, such as through color saturation, “darkening,” desaturation, contrast, brightness, and any other display quality without departing from the spirit and scope thereof.

In the illustrated example, the display of the content 126 is darkened successively in the second and third stages 404, 406. Therefore, the display of the content 126 in the second stage 404 is darker than the first stage 402 and the display of the content 126 in the third stage 406 is darker than the second stage 404. In this way, the display of the content 126 gives an indication of a relative level of the hierarchy that is currently being displayed without adding “chrome,” e.g., additional description showing a file path in the user interface 120. Although darkening has been described, it should be readily apparent that a wide variety of techniques may be used to modify a display of content to indicate a relative level in a hierarchical menu that is concurrently displayed with the menu.

FIG. 5 is an illustration of the mobile communications device of FIG. 1 in an example implementation 500 in which menu items are configured to follow inertia of a scrolling user interface. The illustration 500 includes first, second, and third stages 502, 504, 506. In the first stage 502, a gesture is input using the user's finger 208 to cause the user interface 120 to scroll upward. Before input of the gesture, the first and second menu items 122, 124 are shown in their entirety.

In response to this gesture, the user interface 120 is scrolled in the second stage 504. In response to this scrolling, the first and second menu items 122, 124 “follow” the inertia of the scroll such that at least a portion of the items is no longer displayed. Thus, the first and second menu items 122, 124 follow the user interface 120 in the direction of the scroll so that a portion of the items is no longer displayed. However, at least a portion of one or more of the first and second menu items 122, 124 is continued to be displayed during the scroll. Thus, although the first and second menu items 122, 124 follow the inertia of the scroll the scroll is allowed to continue beneath the menu items so that at least a portion of the items continue to be displayed.

Once the scroll is completed, the first and second menu items 122, 124 are again displayed in their entirety. For example, as the scroll slows the first and second menu items 122, 124 may be animated to return to view in a manner that follows the scroll of the user interface 120. A variety of other examples are also contemplated without departing from the spirit and scope thereof.

Example Procedures

The following discussion describes user interface techniques that may be implemented utilizing the previously described systems and devices. Aspects of each of the procedures may be implemented in hardware, firmware, software, or a combination thereof. The procedures are shown as a set of blocks that specify operations performed by one or more devices and are not necessarily limited to the orders shown for performing the operations by the respective blocks. In portions of the following discussion, reference will be made to the environment 100 and systems 200-500 of FIGS. 1-5, respectively.

FIG. 6 is a flow diagram depicting a procedure in an example implementation in which content has different amount of display richness when displayed with different levels of a hierarchical menu. Content is displayed by a computing device in conjunction with a first level of a hierarchical menu in a user interface on a display device of the computing device (block 602). As shown in the first stage 402 of FIG. 4, for instance, the first and second menu items 122, 124 are displayed in conjunction with content 126 on the display device 110. The first and second menu items correspond to a first level (e.g., a root level) of the hierarchical menu and represent a primary action and a control to navigate to another level of the hierarchical menu.

Responsive to receipt of an input to navigate to a second level of the hierarchical menu that is a sublevel of the first level, the second level is displayed in conjunction with the content on the display device, the content having a reduced display richness when displayed in conjunction with the second level than when displayed in conjunction with the first level (block 604). Continuing with the previous example, the second menu item “more” of the first stage 402 is selected to navigate to the second level of the hierarchical menu. As shown in the second stage 404, the content 126 is displayed to have a reduced display richness (darker in this example), which indicates “where” a currently displayed level of the hierarchy “fits in” to the hierarchy as a whole. For instance, in the system 400 of FIG. 4 successively darker displays of the content 126 indicate lower levels of the hierarchy. A variety of other examples are also contemplated.

Example Device

FIG. 7 illustrates various components of an example device 700 that can be implemented in various embodiments as any type of a mobile device to implement embodiments of devices, features, and systems for mobile communications. For example, device 700 can be implemented as any of the mobile communications devices 102 described with reference to respective FIGS. 1-5.

Device 700 further includes communication interface 704 that can be implemented as any one or more of a wireless interface, any type of network interface, and as any other type of communication interface. A network interface provides a connection between device 700 and a communication network by which other electronic and computing devices can communicate data with device 700. A wireless interface enables device 700 to operate as a mobile device for wireless communications.

Device 700 also includes one or more processors 706 (e.g., any of microprocessors, controllers, and the like) which process various computer-executable instructions to control the operation of device 700 and to communicate with other electronic devices.

Computer-readable media 708 provides data storage to store content and data 710, as well as device applications and any other types of information and/or data related to operational aspects of device 700. For example, an operating system 712 can be maintained as a computer application with the computer-readable media 708 and executed on processor 706. Device applications can also include a communication manager module 714 (which may be used to provide telephonic functionality) and a media manager 716.

Device 700 also includes an audio and/or video output 718 that provides audio and/or video data to an audio rendering and/or display system 720. The audio rendering and/or display system 720 can be implemented as integrated component(s) of the example device 700, and can include any components that process, display, and/or otherwise render audio, video, and image data. Device 700 can also be implemented to provide a user tactile feedback, such as vibrate and haptics.

Generally, the blocks may be representative of modules that are configured to provide represented functionality. Further, any of the functions described herein can be implemented using software, firmware (e.g., fixed logic circuitry), manual processing, or a combination of these implementations. The terms “module,” “functionality,” and “logic” as used herein generally represent software, firmware, hardware or a combination thereof. In the case of a software implementation, the module, functionality, or logic represents program code that performs specified tasks when executed on a processor (e.g., CPU or CPUs). The program code can be stored in one or more computer readable memory devices. The features of the techniques described above are platform-independent, meaning that the techniques may be implemented on a variety of commercial computing platforms having a variety of processors.
